It does mean a thing

Some notes on software and beyond

Sergey Lisitsyn

Education

  • 2012 – 2014, MSc, Samara State Aerospace University, Samara, Russia.
    Thesis: Inductive transfer of classification models.
    Investigated the problem of inductive transfer via non-linear dimensionality reduction. Formulated kernel-based variation of the local tangent space alignment dimension reduction algorithm. Developed a fast parallel implementation of the proposed method [2].
  • 2008 – 2012, BSc, Samara State Aerospace University, Samara, Russia.
    Thesis: Traffic sign recognition using support vector machines.
    Composed a traffic sign recognition model based on the multiclass support vector machine classifier, the histogram of oriented gradients features and the homogeneous kernel mapping procedure [1]. The model has been successfully (top performance for non-neural methods back then) applied to the German Traffic Sign Recognition Benchmark (GTSRB) dataset.

Experience

Working

  • 2014 – present, Software engineer, Yandex, Moscow, Russia.
    Development of internet-scale machine learning infrastructure for advertisement. Extensive experience of data analysis, high-performance systems and practical machine learning.
  • 2012 – 2014, Software engineer, Smart Solutions, Samara, Russia.
    Initial design and further development of a scheduling system based on high-throughput messaging. Development of a web-based railroad scheduling application from the scratch. Comprehensive experience of concurrent systems design, optimization and basics of team management.
  • 2011 – 2012, Software engineer, NetCracker, Samara, Russia.
    Defects resolution, documentation improvements and various development tasks related to an operations support system that is made on top of the Java EE stack. Decent experience of large-scale systems engineering support.
